Bloodgorged is a Force affinity legendary from the Undead Hordes faction. Bloodgorged is known for his 1 shot capability from his A3. This ability hits extremely hard and ignores all defence and blocks revive. Provided you can keep him alive he is a menace in the Arena.
Bloodgorged was buffed in July 2020 to have his A2 as an AOE skills as well that has vastly improved his kit in other content as he can now lock out skills on enemy waves in dungeons.
In order to land his decrease def A1 and put enemy skills on cooldown you do need accuracy. If you are building just for the A3 nuke in Arena ignore accuracy and go full crit rate and crit damage.
